ZyWALL USG 100/200 Series User’s Guide

Use the VRRP Group Add/Edit screen to add or edit VRRP groups.

• You can only use interfaces that have static IP addresses. In addition, you should set the 

static IP address to the IP address of the virtual router.

• You can only enable one VRRP group for each interface.

• You can only have one active VRRP group for each virtual router (VR ID).

The Device HA Legacy Mode Add or Edit screen lets you configure a VRRP group. To 
access this screen, click Device HA > Legacy Mode > Add (or Edit).

Add icon

This column provides icons to activate, deactivate, add, edit, and remove VRRP 
groups.
To activate or deactivate a VRRP group, click the Active icon next to the group. 
Make sure you click Apply to save and apply the change. Activating a VRRP group 
has the ZyWALL monitor the connection of the group’s interface. Each interface 
must have a static IP address and be connected to the same subnet as the group’s 
interface on the other ZyWALL. 
To add a VRRP group, click the Add icon at the top of the column. The VRRP 
Group Add/Edit screen appears.
To edit a VRRP group, click the Edit icon next to the group. The VRRP Group 
Add/Edit screen appears.
To delete a VRRP group, click the Remove icon next to the group. The web 
configurator confirms that you want to delete the VRRP group before doing so.

Server Address

Enter the IP address or fully-qualified domain name (FQDN) of the ZyWALL from 
which to get configuration and subscription service updates (for services to which 
the backup ZyWALL is subscribed). Usually, you should enter the IP address or 
FQDN of a virtual router on a secure network.

Server Port

Enter the port number that the ZyWALL you specified in the Server Address field 
uses for Secure FTP. Every ZyWALL in the virtual router must use the same port 
number. If the master ZyWALL changes, you have to manually change this port 
number in the backups.

Password

Enter the password used to verify other ZyWALLs during synchronization. This 
password is different than the one that is used for authentication in the VRRP 
group. Every ZyWALL in the virtual router must use the same password. If you 
leave this field blank in the master ZyWALL, it does not allow any backup ZyWALLs 
to synchronize from it. If you leave this field blank in a backup ZyWALL, it cannot 
synchronize from the master ZyWALL. 

Auto 
Synchronize

Select this to get configuration and subscription service updates automatically from 
the specified ZyWALL according to the specified Interval. The first synchronization 
begins after the specified Interval; the ZyWALL does not synchronize immediately.

Interval

This field is only available if Auto Synchronize is checked. Type the number of 
minutes to wait between synchronizations.
